Graphics / Transform matrix behaves differently for VertexArray and Text

« on: December 24, 2019, 07:08:07 am »

In this code snippet:

    sf::Text      text{ "text", font };
    sf::Transform transform{ 1, 0, 0, 0, -1, 0, 0, 0, 1 };
    sf::View      view{ sf::FloatRect{-100, -100, 200, 200} };

    text.setFillColor(sf::Color::Red);
    view.setViewport(sf::FloatRect{0, 0, 1, 1});
    window.setView(view);
    window.draw(text, transform);

the text is being displayed upside-down as intended. When I change transform to:

sf::Transform transform{ 1, 0, 0, 0, -1, 0, 0, 0, 0 };

the text is not displayed any more. If I replace sf::Text with sf::VertexArray, vertices are displayed. Why there is a difference in behavior between these two Drawable types?

Thanks. I had hard time finding this before, but now your answer directed me to the description of sf::err(), which makes it clear. Maybe it could be referenced somewhere at top level of documentation as a general way of handling error conditions.

General / Text error messages from some functions.

« on: September 05, 2015, 11:24:50 am »

I've built my first SFML program and I noticed that functions like loadFromFile send a text error message to the console when they fail. I can't find a description of this side effect in the documentation. Is this text being sent to std::cerr stream? Is there an option to throw an exception instead or in addition to this error message?
